[gentoo-user] Suppressing some "emerge" output

[Dr Rainer Woitok <rainer.woitok@gmail.com>]

Greetings,

after a recent KDE upgrade  among other new packages  "emerge"  also in-
stalled "dev-qt/qtwebengine" as a new dependency.  Since on my five year
old laptop  this package requires about  6 hours 20 minutes to build,  I
decided to slightly redesign my package managing script and to use bina-
ry packages for long bilding dependencies I build with default USE flags
anyway.

It works,  but is there a way (short of using "|grep -v ...") to prevent
"emerge" from spitting  plenty of noisy  but rather  irrelevant progress
messages to  standard output  (which it  also logs  to "/var/log/emerge-
fetch.log")?   Since I want to save the "emerge" logs  and since "man e-
merge" is less than helpful  with respect to option "--quiet"  ("Results
may vary,  but the general outcome is a reduced or condensed output from
portage's displays.") I have yet hesitated to enable this option.  Would
it help at all?   Would "emerge" still write logs to  "/var/log/portage/
*/*" and  "/var/log/emerge.log"?   Is there another option  or "FEATURE"
setting I should use?

Any suggestions welcome :-)

Sincerely,
  Rainer
